Can I add other sensors to a Holfuy station?

Yes, the Holfuy main panel has many universal input ports: SPI, I2C, One wire, A/D-s, and we can write the driver for it on request.
But the sensor has to be low-power. Please contact us for details!

What happens when a station runs out of charge?

When a station doesn't get enough sunshine it will be discharged and go to Soft Sleep mode, after some sunny days it will automatically wake up from this mode.
- Soft Sleep mode: The station will only send one life signal package per day (temperature, system power, network signal strength). This state can be sustained with a little sunshine. When the battery is nearly depleted, the station goes to Deep Sleep mode.
- Deep Sleep mode: The station sends nothing in this mode. It will wake up after some sunny days or a manual recharge.

How often does a station updates it's measurement data?

The default update interval is 2 minutes, but you can modify it (min. 1 minutes). The server generates the averages then.

Can I analyze the archive data of my station?

Yes, please visit your station's analytics page after login.

How much data traffic is generated by a station?

Less than 10 MBytes/month with a standard station.

What happens if my Holfuy station receive an SMS?

It will be visible at the station's admin page. On request we can forward every single SMS to your e-mail account.

What does "Holfuy" mean?

Holfuy is a pun/wordplay. "Hol" means "where", "fuj" means "blows". We changed the "j" to an "y". Finally Holfuy means "Where does the wind blow?" :)
